ABSTRACT:
A dump spreader achieves both slow speed spreading and high speed dumping of material from truck body 10 having a bottom conveyor 11 and hopper-shaped side walls. A fixed rear wall 12 secured to the side walls closes the rear end of the body above the conveyor, and the rear wall has a bottom opening 13 approximately the width of the conveyor and extending from the conveyor upward to one-half to three-quarters of the height of the rear wall. A vertically movable door 20 supported on the rear wall opens and closes the opening; and a hydraulic system raises and lowers the door to set the door at a desired low level above the conveyor for spreading, to raise the door fully so the conveyor can move a substantial depth of material rapidly through the opening for dumping, and to close the door through a depth of material on the conveyor after a partial dump. A spinner 15 operable in the spreader mode is detachable from the body via a pin and slot arrangement that also securely supports the spinner in place for spreading.
